Scientists have discovered that the presence of large fish predators can reduce stress on baby fish.

The researchers – from the ARC Centre of Excellence for Coral Reef Studies, James Cook University and the University of Glasgow- have found that physiological stress on baby fish can be reduced by more than a third if large predatory fish are around to scare off smaller, hungry predators, known as mesopredators.
